I'm supprised you found DIP8 chips in those sizes. I tried to buy them
and could not find them, granted I was looking at single quantity items.
Instead, I've orderd some SOIC8 parts and some adapters for them. With
those Items in hand, I started designing the 'dual-flash' module that
has passed this list a few times before.
I am currently trying to incorporate Peter's suggestions into my design
which should be done in a week or so.
I think your idea is true and great, but bundled with the PCB i'm
designing would be even beter and should cost about the same, as SOIC
parts are cheaper then DIP8 parts it seems.
Just think of it, handing out a little adapter, where the user can
insert his own DIP8 flash and with the change of a switch/jumper test
coreboot! Just replace the jumper and their trusted old bios returns.
Just my two cents :)
